An anniversary turned into drama on Sunday in the United States.
A man opened fire at the Colorado holiday, killing six people before turning the gun on him, police said.
Colorado Springs police received an emergency call in the morning from a mobile home park, where they found six adults shot dead and a seriously injured man.
The latter was taken to hospital where he died of his injuries.
No injuries among the children
The first elements of the investigation revealed that the shootings broke out in one of the mobile homes, where families were gathered to celebrate a birthday.
"The suspect, boyfriend of a woman among the victims, drove to the scene, started shooting at the guests and then killed himself," police said.
"We are still investigating to determine the motive."
None of the children present were injured, police said, and all were taken in by family members.
More than 43,000 gun deaths were recorded in the United States last year, including suicides, according to figures from Gun Violence Archive, a research association on gun violence.
